ABSTRACT:
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to temperature control systems and more particularly pertains to a new climate control device for maintaining a temperature within a room at a constant level.
2. Description of the Prior Art
The use of temperature control systems is known in the prior art. More specifically, temperature control systems heretofore devised and utilized are known to consist basically of familiar, expected and obvious structural configurations, notwithstanding the myriad of designs encompassed by the crowded prior art which have been developed for the fulfillment of countless objectives and requirements.
Known prior art includes U.S. Pat. No. 5,310,111; U.S. Pat. No. 4,957,238; U.S. Pat. No. 4,756,474; U.S. Pat. No. 4,643,353; U.S. Pat. No. 3,346,185; and U.S. Pat. No. 3,653,588.
In these respects, the climate control device according to the present invention substantially departs from the conventional concepts and designs of the prior art, and in so doing provides an apparatus primarily developed for the purpose of maintaining a temperature within a room at a constant level.
SUMMARY OF THE INVENTION
In view of the foregoing disadvantages inherent in the known types of temperature control systems now present in the prior art, the present invention provides a new climate control device construction wherein the same can be utilized for maintaining a temperature within a room at a constant level.
The general purpose of the present invention, which will be described subsequently in greater detail, is to provide a new climate control device apparatus and method which has many of the advantages of the temperature control systems mentioned heretofore and many novel features that result in a new climate control device which is not anticipated, rendered obvious, suggested, or even implied by any of the prior art temperature control systems, either alone or in any combination thereof.
To attain this, the present invention generally comprises a central unit having a housing with a lower portion including a bottom face and a peripheral side wall coupled to a periphery of the bottom face and extending upwardly therefrom. As shown in
FIG. 1
, an interior space and an open top are thus defined for being selectively covered via a lid with an associated lock for locking purposes. The central unit further includes a vacuum pump mounted within the interior space of the housing. Such vacuum pump is adapted for generating a vacuum upon actuation. Associated therewith is a cooling fan mounted to the side wall of the housing for ventilating the interior space thereof upon actuation. Connected between a power source and the vacuum pump and the cooling fan is an actuation switch. Such switch is positioned on the side wall of the housing for selectively actuating the same. The central unit further includes a plurality of linearly aligned ports mounted on the peripheral side wall of the housing and connected to the vacuum pump. Note
FIG. 2. A
plurality of normally closed vacuum valves are each connected between one of the ports and the vacuum pump for allowing communication between the vacuum pump and the port only during the receipt of an activation signal. Associated therewith is a plurality of normally open dump valves each connected between one of the ports and the vacuum valve connected thereto. The dump valves serve for allowing communication between the port and free space only during the lack of receipt of the activation signal. Next provided is a plurality of panels each positioned within one of the rooms of the household. Each panel is equipped with a thermostat mounted thereon and is connected to the vacuum pump valve and the dump valve associated with one of the ports. In use, the thermostat generates the activation signal upon a current temperature within the associated room being greater than a predetermined amount. Each of the panels further includes a normally closed vent switch adapted to preclude the transmission of the activation signal to the vacuum pump valve upon the depression thereof. Finally, a plurality of vent assemblies are provided each including a frame mounted within a heating vent in one of the rooms of the household. As shown in
FIG. 1
, a plurality of vanes are pivotally mounted within the frame and have an unbiased open orientation for allowing the flow of heat into the associated room. The vanes further have a biased closed orientation for precluding the flow of heat into the associated room. A pneumatic servo is connected to each of the vanes and remains in communication with one of the ports of the housing via a conduit. In use, the servo is adapted to transfer the vanes of the vent assembly to the closed orientation thereof only upon the receipt of vacuum via the associated port of the central unit.
There has thus been outlined, rather broadly, the more important features of the invention in order that the detailed description thereof that follows may be better understood, and in order that the present contribution to the art may be better appreciated. There are additional features of the invention that will be described hereinafter and which will form the subject matter of the claims appended hereto.
In this respect, before explaining at least one embodiment of the invention in detail, it is to be understood that the invention is not limited in its application to the details of construction and to the arrangements of the components set forth in the following description or illustrated in the drawings. The invention is capable of other embodiments and of being practiced and carried out in various ways. Also, it is to be understood that the phraseology and terminology employed herein are for the purpose of description and should not be regarded as limiting.
As such, those skilled in the art will appreciate that the conception, upon which this disclosure is based, may readily be utilized as a basis for the designing of other structures, methods and systems for carrying out the several purposes of the present invention. It is important, therefore, that the claims be regarded as including such equivalent constructions insofar as they do not depart from the spirit and scope of the present invention.
Further, the purpose of the foregoing abstract is to enable the U.S. Patent and Trademark Office and the public generally, and especially the scientists, engineers and practitioners in the art who are not familiar with patent or legal terms or phraseology, to determine quickly from a cursory inspection the nature and essence of the technical disclosure of the application. The abstract is neither intended to define the invention of the application, which is measured by the claims, nor is it intended to be limiting as to the scope of the invention in any way.
It is therefore an object of the present invention to provide a new climate control device apparatus and method which has many of the advantages of the temperature control systems mentioned heretofore and many novel features that result in a new climate control device which is not anticipated, rendered obvious, suggested, or even implied by any of the prior art temperature control systems, either alone or in any combination thereof.
It is another object of the present invention to provide a new climate control device which may be easily and efficiently manufactured and marketed.
It is a further object of the present invention to provide a new climate control device which is of a durable and reliable construction.
An even further object of the present invention is to provide a new climate control device which is susceptible of a low cost of manufacture with regard to both materials and labor, and which accordingly is then susceptible of low prices of sale to the consuming public, thereby making such climate control device economically available to the buying public.
Still yet another object of the present invention is to provide a new climate control device which provides in the apparatuses and methods of the prior art some of the advantages thereof, while
